Summary
Built in 1955 by the Natural Resources Conservation Service, this earth dam stands at 16 feet high and spans 700 feet in length. With a storage capacity of 160 acre-feet, it serves the primary purpose of regulating water flow and providing flood control in the area.
Managed by the South Dakota Department of Environment and Natural Resources, Sd Noname 222 is deemed to have a low hazard potential and is currently assessed as "Not Rated" in terms of condition. While its emergency action plan status and risk assessment measures are not specified, the dam is regularly inspected, permitted, and enforced by the state regulatory agency. With a maximum discharge capacity of 2500 cubic feet per second, this dam plays a crucial role in water resource management in the region.
Located within the St. Paul District of the US Army Corps of Engineers, Sd Noname 222 is a vital infrastructure that contributes to the overall water resource and climate resilience of South Dakota. As a key component of the local water management system, its presence ensures the safety and well-being of surrounding communities while also supporting agricultural and environmental needs in the area.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
